The Virgin Oceanic submarine represents a transformational technological advance in submarine economics and performance. The submarine provides the currently unequalled capability to take humans to any depth in the oceans and to truly explore. It utilises the latest in composite technology and a completely unique flying wing to literally fly within the Ocean environment; creatures living here such as dolphins, whales and rays have shown us this winged approach is the best and most elegant way to range the seas. The submarine is many times less expensive to manufacture and operate than any of its less capable counterparts and is in harmony with its environment.

The submarine was originally commissioned by Sir Richard’s close friend and fellow adventurer Steve Fossett who had intended to complete the first solo dive to the depths of the Mariana Trench. Sir Richard intends to finish what his friend started and then go on to help explore and unlock the wonders of the Oceans still unknown to humankind or science.

The vehicle is a unique design made from 8,000 pounds of carbon fibre and titanium. The pressure at the bottom of the deepest trench is over 1,000 atmospheres – the quartz dome alone is under 13 million pounds of pressure, the weight of three space shuttles.

Designed by Graham Hawkes, it is the only piloted craft in existence that has ‘full ocean depth’ capability. The one person sub has an operating depth of 37,000ft (7 miles) and is capable of operating for 24hrs unaided. Once fully descended, the submarine’s hydroplanes (the equivalent of wings for submarines) and thrusters will allow it to ‘fly’ up to 10km over the ocean floor whilst collecting video and data, something submersibles could only dream of.

At these depths, each individual part of the sub must be able to withstand enormous pressures, 1500 times that of an aeroplane, and protect its pilot from the extreme conditions just inches away. As Sir Richard and Chris each pilot the sub to the bottom of our planet, they will be aware that should anything go wrong, there is no rescue team that can reach them; whilst backed up by a mission crew, once at depth, the pilot and craft are alone. Full pressure testing will be conducted over the next three months.

The craft will cruise at a max of 3 knots and can dive 350ft per minute. At that speed, a dive to the bottom of the Marianna trench and back is estimated to take about five hours.
